WIRE-POLISHING. MACHINE.

Patented June 22, 1909.

Application filed February 28, 1908. Serial No. 418,209.

To all 'uihom itvriay concern: Be it known that I, HENRYJANSSEN, a

citizen ofthe United States, and a resident of the Borough ofW'yo'missing, in the county of Berks and State of Pennsylvania, haveinvented certain new and useful Improvements in Wire-Polishing Machines,of which 7 the following is a s ecification.

My. invention re ates to machines for mechanically polishing the surfaceof passing rods or wire.

The-invention consists in providing in connection with a rotary hollowspindle through which this rod or wire is suitably passed, pivotallymounted arms on said spindle carrying polishing devices adapted to beclosed together uponthe rod or wire bycentrifugal action of said pivotedarms due to rotation of the spindle; and further in providing forreadily varying the olishin'g .pressure thus produced; as fully escribedin connection with the accompanyin drawings, the novel features beingspecifica ly pointed out in the claims. a

Figure 1 is aside elevation of a polishing head embodying my inventionin preferred form. Fig. 2'is a partial lan view of the same. Fig. 3 is ase arate vlew of the weightengaging sleeve. ig.-4 indicatesa modifiedconstruction.

The hollow spindle a, as shown, is mounted v in fixed bearings b 6between which it is provided with a drive pulley 0. At its forward endis secured a carrier-head (1, formed with pivot-jaws e and c in whichare mounted similar centrifugally movable arms f f having polishingdevices fitted thereto.

These devices as indicated comprise similar die-blocks g 9 having theiropposed faces grooved to suitably contact with the surface of the rod orWire, and'e'achentered .in a pocket It formed in a forwardly projectedportion of an arm f ,*the blocks being backed by pivotpins h in therespective pockets, upon which.

they are free to rock so as to insure their hearing uniformly againstthe interposed rod or wire when in action. T Upon the rear- Wardlyextending ortions of each arm f is inounted a weight in the form of asliding sleeve, the degree of pressure exerted through centrifugalaction, upon the passing rod or wire, at a given speed ofrotation of thespindle, being determined, by the location of these weights at agrateror less distance from the pivotal connections f f of the arms. To rovidefor conveniently adjusting sleeve without interfering with the freeswingthe of the arms due to centrifugal force; weights k as shown beingprovided with grooves k, and a pair of fingers being arrangedfork-likein each groove. 7 The adjustment of the sleeve m on the s indleto thus vary the polishing pressure, s ould be so effected that it may.be conveniently accomplished Without interference with the running. ofthe machine; and for this purpose I employ a non-rotatingsleeve-adjustmg device consisting of a sleeve-en aging slide 17, movablein a suitable guideate g, fixed to the top of bearing b. This slide, asshown, is provided with a clamping screw p extending through a slot g inthe plate q, and its hooked outer end p is engaged in a circular groovem in said sleeve so that the position of the latter may be readilychanged as desired while the sleeve'is being rotated surfaces, thoughother suitable material may 4 be employed. The swing of the pivoted armsmay be positively limited as by means of slots (1 therefor in carrierhead d, as indicated in Fig. 1. Though the intermediate pivoting of thearms to the carrier-head, as described, is preferred, they may bepivoted thereto at one end for instance as indicated in Fi 4, eachpolishing device g in the latter case" eing extended around, the rod orwire operated upon so as to bear against the opposite side thereof undercentrifugal action, as indicated. Other modifications may obviously bedevised without departing from the invention.

What. I claim is 1. A wire or -rod polishing machine com prising ahollow rotary spindle and centrifugally movable arms pivoted thereto andpro; vided with polishing devices, said devices being closed together atthe spindle axis by the pivotal centrifugal movement of the rotatedarms.

2, A wire or rod polishing machine comprising a hollow rotary spindleand centrifugally movable arms pivoted thereto and provided withpolishing devices and adjustable weights, said devices being closedtogether at the spindle axis by the pivotal centrifugal movement of therotatedarms.

3. A wire or rod polishing machine comprisinga hollow rotary spindle,centrifugally movable arms pivoted thereto and provided with polishingdevices, Weights slidable on said arms, and a longitudinally adjustablesleeve on said spindle engaging said weights.

4. A wire or rod polishing machine comprising a hollow rotary s indle,centrifugally movable arms pivoted t ereto and )rovided with polishingdevices, weights sli able on said arms, a longitudinally adjustablesleeve on said spindle engaging said weights, and non-rotatlng adjustingmeans for said sleeve.

5. A wire or rod polishing machine comprising a hollow rotary spindle,oentrifugally movable arms pivoted thereto and having forwardlyrojecting ortions provided with polishing evices and rearwardlyextending portions provided with slidable weights, and

30 a longitudinally adjustable sleeve on said spindle engaging saidweights, substantially as set forth.

' 6. A wire or rod polishing machine comprising a hollow rotary spindle,centrifugally movable arms pivoted thereto and having with polishingdevices, grooved weights slidable on said arms, and a longitudinallyadjustable sleeve on said spindle having forked fingers engaging saidgrooved Weights.

8. A wire or rod polishing machine comprising a hollow rotary spindleand centrifugally movable arms provided with polishing devices, saiddevices being closed together at the spindle axis by the centrifugalmovement of the rotated arms,

In testimony whereof, I affix my signature, in the presence of twowitnesses.
